What is a common use for beta-blockers in pharmacotherapy?

Beta-blockers are commonly used in pharmacotherapy primarily to manage hypertension, which is high blood pressure. These medications work by blocking the effects of epinephrine (adrenaline) and slowing the heart rate, which reduces the heart's workload and helps lower blood pressure. By relaxing the blood vessels and reducing the heart rate, beta-blockers effectively lower blood pressure and decrease the risk of complications associated with hypertension, such as heart attacks and strokes.

In addition to their role in hypertension management, beta-blockers may also have other indications, such as treating certain types of heart arrhythmias, heart failure, and even anxiety-related conditions. However, their primary function in the context of this question focuses on blood pressure regulation.

Other options like lowering cholesterol, treating diabetes, or relieving pain do not align with the primary pharmacological effects of beta-blockers and are managed by different classes of medications.
